It features a 5\/8 inch cutting diameter, a 2-1\/8 inch length of cut, and an AlTiCrN coating that provides excellent heat and wear resistance at elevated cutting temperatures. The 38-degree helix angle promotes smooth chip evacuation and reduces cutting forces, making this tool well-suited for demanding finishing and semi-finishing operations. It is installed and operated by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use on CNC machining centers and manual mills where high material removal rates and tight tolerances are required. The variable index geometry helps reduce harmonic chatter during deep-cut passes. With a single-end design and right-hand flute direction, it is a direct-install tool for standard R8, CAT, BT, and HSK toolholding systems accepting a 5\/8 inch shank. It belongs to the ACCUPRO HS Series, which is optimized for hardened steels and exotic alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrN coating delivers superior oxidation resistance and hardness at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e5 flutes with variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip evacuation in deep slots and pockets\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear life beyond high-speed steel tools\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling operations without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral, compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production cutting tool for CNC machining centers and manual mills accepting a 5\/8 inch straight shank end mill holder.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates tool wear and compromises surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches \/ 15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/8 inches (2.1250 inches \/ 53.98 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 311741\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738793181490,"sku":"311741","price":246.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25435d7e993b45926585fc3c67e2fa85.jpg?v=1788804568","url":"https:\/\/voomisupply.com\/products\/accupro-311741-square-end-mill-5-8-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
